EMPs

If you’ve ever watched The Matrix or Ocean’s Eleven, you’ll be familiar with EMP weapons — pulses of intense electromagnetic radiation that melts any nearby conductors, which can be found in just about any electrical system or electronic device. Despite their sci-fi-like portrayal by Hollywood, EMP weapons are very real, and very capable of destroying computers or knocking out a power grid. That’s why the Fraunhofer Institute in Germany has now created a device that can defend against EMP attacks.
